Some patio fancy-ing

My twin sister, Cate, recently bought a very cute house about a mile away from me in the Los Angeles neighborhood of Silver Lake.

The house was built in 1926, and she is the second owner.  Needless to say, that doesn't happen often in Los Angeles!

Renovations and improvements are under way and I've been assigned all sewing duties!  I'll be making some curtains and throw pillows, but the biggest task is making a huge cushion to have on a built in bench that's on the back patio.

I'm going to put this tutorial to the test, as the cushion will measure almost 9.5 feet by 3 feet!   I'm going to use this fabric - does anyone know who makes/designs it?  There's nothing printed on the slevedge and I called the store where I bought it (Michael Levine's in downtown Los Angeles) and they said that the tube didn't have the info either... I'll need to head down there again soon, so I'll double check that, but meanwhile, anyone recognize it?  It also comes in an orange and yellow colorway, it's 54" wide and it's got a canvas-y feel to it.  It's truly beautiful!
